System action

CLSDST the node except for intervention-required conditions. On intervention-required processing, the operation continues normally after the node (terminal) is made ready.

Operator response

Attempt to OPNDST the node and continue operation if possible; if not possible, see Problem determination. For intervention-required processing, make the node ready and processing should continue normally. Obtain IMS Transaction Manager trace of the failure.
